Combine egg whites and sugar in heat-safe mixing bowl. Fill a saucepan 1/3 way full of water and bring to a simmer. Make sure that the mixing bowl fits inside the pan nicely because if the pan is too big, water will splash and it could get dangerous! Place mixing bowl into pan and whisk sugar and whites together until sugar is fully dissolved and mixture is slightly frothy. Transfer mixing bowl to stand mixer fitted with whisk attachment. Whisk on medium-high until mixture is fully cooled and has a thick, meringue-like texture. Add the butter a piece at a time, mixing well after each addition. Switch to a paddle attachment, add vanilla bean, and beat for an additional 2-3 minutes.

Assembling the Macarons:

Spread a very thin layer of butter cream on one shell. Add four small dollops of butter cream onto four edges of cookie. Place a raspberry on each each of the cookie (you can cut them lengthwise if they look to large or awkward inside the cookie). Sandwich the cookie together and pipe small dollops of frosting in spaces between raspberries. Apply edible gold glimmer dust with a dry paintbrush, lightly covering entire top cookie. Place a small dollop of buttercream on the top of a raspberry and stick on top of cookie. Lastly, dip paintbrush in gold dust again and flick on top of cookie and raspberry.
